F23 vs h22

[toycar]

I'd dog you even more for putting an H head on an F block. There are MANY reasons why that is a bad idea. I don't care how many people say "I did it and it's fine"... it's a bad idea.

And you milled a perfectly good head? Great. Now as soon as you overheat that motor once, that head is trash. You'll never be able to shave material off of it again. Also, milling throws off your valve timing. That's one of the worst ways to increase compression, unless you're expecting to build a disposable motor.



The Type S and Euro R H22s make 220 crank hp. But they're also stupidly expensive compared to the 200hp regular H22. The S and R have higher compression, better cams (same cams as the 200hp F20B), and a better intake manifold. I'm sure there are other differences as well, but those are the primary ones.

Even then, you'd need another 15whp or so to hit 200whp. That could be done with a Bisimoto header, but once all is said and done, you're looking at damn near $5000!


I agree about the 300 being a nice number. That's about where I'd stop for a DD. More than that, and you'll have a hard time keeping the tires planted.
Forged is the way to go... and sleeved, too. The stock sleeves can hold quite a bit, but with turbo pistons knocking around in there, they're the next weak link in the motor design when it comes to turbo.
Also, proper turbo pistons have a low silicon content, which makes them very strong, but they also expand... which means they'll be fitting rather loosely in the sleeves until the engine reaches operating temperature. That can take a toll on both pistons and sleeves over time with a daily driver. Unless there have been advances in piston construction that I am not aware of.

The advances have been made in the rings, ring gap and hardness of the metal to work with expansion. That problem can be addressed with the hone of the block as well if your machine shop is worth a shit. Take them the pistons, rods, rings and block and they should give it back ready to roll.

Also, that problem is more prone in v engines, rather then inline.

Good comment though, most folks don't think much about the piston expansion issue. That's 99% of the reason letting your turbo car warm up is so important.

wow this thread is awsome f vs h nothing better i would rather listen to. lol i would rather go with a f22a then that f23 engine never even thought about just dosent get that attention for a reason. but i guess if you have the motor and willing to give your self a head ache because you dont want to listen to whats said go ahead TURBO that B*** and watch it BLOW.. there goes money down the drain.

I've probably turbo'd more n/a cars then your entire family has owned. Set if up right, and it will not blow.

ok smart a**. since you want to flame you should learn how to SPELL. Now i didnt say nothing wrong about turbo but incase you cant read either this is what i said....

but i guess if you have the motor and willing to give your self a head ache because you dont want to listen to whats said go ahead TURBO that B*** and watch it BLOW.. there goes money down the drain.

now with that out the way if you have ALOT of MONEY then sure go ahead build it right and boost that F23 and im sure youll get plenty of HP.

Panties in a bunch? I didn't spell anything wrong, my stupid Droid put if in place of it.

Message stands. Turboing a motor doesn't equal fail if you know how to do it and what your doing.

How many n/a cars have you made turbo?

I did not have it milled as far as they can go just enough to give me a fresh serfice and make the compression a little higher.. so if it dose over heat I can have it milled Aegean but Only dumbasses and ignorant women let cars overheat...

toycar, you need to chill, he did not attack you or your experience, nor did he ever make any reference to you or your comments, or make any claims that he is better than you in anyway.
this is the second time i have seen you jump into the: "i am better than you are mode, all because i have built more motors than you".

please calm down, and be friendly, he NEVER once made any statement against you at all untill you attacked his post, he simply summed up what we were all saying from the beggining

[gloryaccordy]

Jeeez!!!! Touchy touchy

You act like I am both wrong and the aggressor here. If you build a turbo motor correctly it will not blow up, and I have been working with turbocharging cars for almost 20 years.

So what? You trying to tell me that you don't speak from your experiences?

And I'm still wondering where I attacked anyone. I have truthfully built a lot of turbo systems, and when done correctly they do last.

toycar is just stating facts. He is right that if you turbo your car right you wont kill the engine. If he stated that he turboed allot of cars thats not really saying I am better then you its just saying I know what I am doing and am not a nube posting shit that is wrong just to post stuff and sound smart.

ugh that was painful to read

Its true

[deevergote]

He's not talking about the meaning of your words... just the words themselves. It's almost impossible to understand what you type.


Anyway, a stock-block turbo setup will fail eventually, even set up properly. Well, every motor will fail eventually, but turbo does certainly increase the wear.

To be honest, the only use for this F23A1 is turbo, unless you want to throw a LOT of money at it for a level of performance that would me much cheaper to achieve with another motor.

[Tippey764]

Its true

No, because your lack of any grammar or spelling made it much harder to read

[sulimed]

how the hell this thread get to five pages.

OP, why are you still here trying to make or explain your point. this is a 4th gen accord site, and your trying to build a 6th gen accord eng. why not just go to a 6th gen accord site. find a engine build one of there members is doing or have done, and blue print yours from that. this is a great site......but maybe not the best for your engine needs at the moment.
